The Solaris Resource Manager (SRM) was a unbundled, separately licensed product for Solaris 2.6, Solaris 7 and Solaris 8. This product was integrated into the Solaris Operating System with the release of Solaris 9.
The Solaris 10 release adds a new container for Resource Management in the form of Zones and new resource controls, additionally parts of the Resource Management Framework are now started as Solaris 10 services.
Some of the resources sited on this page refernece Solaris 9 Resource Management, however the content will apply to Solaris 10 Resource Management with very few exceptions.

Solaris 10 Update 5 (5/08) introduces CPU caps. CPU caps provide absolute fine-grained limits on the amount of CPU resources that can be consumed by a project or a zone.
Two new controls are added, project.cpu-cap and zone.cpu-cap. The control is represented as 1% of a cpu. 100 represents 1 full cpu when configured for a project, the control is represented as integer where 1 represents a full cpu and .5 represents 50% of a cpu for zones.
the controls are a absolute cap on the cpu resource.
Project CPU cap example:
user.akolb:1234::::project.cpu-cap=(privileged,600,deny)
Sets a 6 cpu limit for the project user.akolb.
Zone CPU cap example:
# zonecfg -z myzone
zonecfg:myzone> add rctl
zonecfg:myzone:rctl> set name=zone.cpu-cap
zonecfg:myzone:rctl> add value (priv=privileged,limit=150,action=deny)
zonecfg:myzone:rctl> end
zonecfg:myzone> info
...
capped-cpu:
[ncpus: 1.50]
rctl:
name: zone.cpu-cap
value: (priv=privileged,limit=150,action=deny)
Sets a one and one half cpu limit for the zone myzone.
# zonecfg -z myzone set capped-cpu=1.25
Sets a one and one quarter cap on the zone myzone.
Dynamically changes a CPU cap for a project:
$ prctl -r -t privileged -n project.cpu-cap -v 80 -i project group.staff
Replaces a cpu cap on the project group.staff, making the new cap 80% of one cpu, reguardless of the number of cpus to which the project has access.
